DC Linearizer Low Noise Filter
External DC power supplies are a known source of RF noise. Our own unique DC Linearizer circuit transforms almost all of that RF noise into a clean DC voltage. The result is then fed to a Low Drop Out regulator circuit. We employ separate regulators for the supply of power to the TOSLINK and coax input circuit, digital and analogue signal processing circuit, and the headphone amplifier circuit. The result is an analogue sound with firmer and deeper bass, more detailed midrange, and crystal clear treble.

High accuracy crystal controlled receiver chip for low jitter.

Many agree that a low jitter ability heavily influences the performance of a DAC. The Bushmaster uses a crystal-controlled receiver with one of the lowest jitter performances possible from a receiver chip. At 50ps few other DACs can match or surpass the Bushmaster in terms of jitter rejection.

Simple Analogue Filter Circuit.

There has been much debate as to how much damage is done to the audio signal by the various digital and analogue filtering networks that are found in a DAC design, and whether filters contribute to grainy high frequencies. The technology used in the Beresford Bushmaster relies instead on a simple HF analogue filter that operates outside any feedback circuit and outside the audio spectrum. This makes the Bushmaster less prone to anti-aliasing filter residues and noise and produces a far cleaner and more detailed treble response.

Asynchronous SPDIF to I2S signal transfer

In order to correct timing and data speed transfer errors the TC-7533 uses a asynchronous buffer with a length of 1024 bits to take care of time period related errors.

Direct Coupled Analogue Output Stage

There are no opamps, muting circuits, or capacitors between the DAC chip and the output sockets to affect the accuracy of the audio signal. This allows the Bushmaster to operate down to 1Hz. The Bushmaster is therefore also suitable for DVD audio applications, which can go down to 5Hz or lower.

High Current Class A-B headphone circuit

The Bushmaster headphone amplifier circuit is designed to drive even the latest high-end headphones and reproduce the musical detail that these headphones are capable of. A generous signal headroom overhead, low noise circuitry, and high output current ability are key factors that make the headphone output on the Bushmaster a major talking point with existing owners.
LED OFF during music playback function

The Bushmaster MKII has a LED OFF function that can be set to operate when there is music playing. So that way, you can ensure that no LED noises can bleed into the sound.
12 Volt battery operation option.

Due to the highly efficient design and low energy requirement placed on the power supply, the Bushmaster is capable of operating from a 12 Volt battery
